Features 1、This 8-way 10A relay controller has normally open and normally closed output 2、Can be used for smart home control, secondary development of mobile phone or computer remote control lights, motors, and other electrical equipment 3、Can be used for computer room power failure detection, can be connected to human body infrared sensor, button switch and smoke alarm output 4、Reliable network connection, network will automatically reconnect if it is off-line 5、In TCP service mode, it can support 4 network connection, using 32-bit MCU Specification Features: This 8-way 10A relay controller has normally open and normally closed output. 8-way switch on-off input. Can be used for smart home control, secondary development of mobile phone or computer remote control lights, motors, and other electrical equipment. Can be used for computer room power failure detection, can be connected to human body infrared sensor, button switch and smoke alarm output. C++ source code is provided. Reliable network connection, network will automatically reconnect if it is off-line. In TCP service mode, it can support 4 network connection, using 32-bit MCU. Very convenient network parameter setting software. Support working in TCP server, TCP client, and UDP mode. Support 4 client connection when working in TCP server mode. Supports user-defined name, no need to record IP number when there are many equipment. Supports user-defined heartbeats packet time, reliable off-line network restore. Can work in switch on-off unvarnished transmission mode. Download three firmware through configuration project, respectively are general firmware, switch on-off unvarnished transmission firmware, access control firmware. General firmware is working in slave mode, using command to control. Switch on-off unvarnished transmission firmware is used in pairs, one input control the other output, each input correspondingly controls other relay output. Access control firmware can connect to four 26 protocol read heads. Specifications: Power Supply: DC 9-24V, ≥2A Input: Can input switch on-off, passive or active, maximum active is 5V.

Product Control Command: Send on1 will open the first way relay, Send off1 will close the first way relay, 2-8 way control method is the same. Send read will read relay state, if return to relay00000001, it means the first way relay is energized, 2-8 way relays are dis-energized. Support time delay control, for example, Send:on1:02, means relay is energized for 2 seconds then dis-energized Send:on: 12 means relay is energized for 12 seconds then dis-energized, the longest delay time is 99 seconds. Application: 1. Can be used in smart home control. 2. Can be used for secondary development of mobile phone or computer remote control lights, motors, and other electrical equipment. 3. Can be used in computer room power failure detection, can be connected to human body infrared sensor, button switch and smoke alarm output. 4. Can be used for access control system, control computer to turn on, and remote control electric appliance. 5. Can smoke alarm output, can meet the human body infrared detector output, 6. Can pick button switch, can pick up any passive switch input, and can also meet the active switch input (connect 5 v active switch amount). 7. Can control by external network, mobile phone remote control (mobile phone APP should developed by yourself). Package Includes: 1 x Relay Controller Package List
